In the early life of rcinlci ed insoles the type llElVlJlfi the "r ale ttonn'nercini success was the Gem iiisrloscd in the patent to Cole No.575,160. dated January 11), 1897. Later other types of reinforcedinsoles were developed such as llm llconomf disclosed in the patent toJohnson No. 849,245, dated April .3 1907, and the lVonder-W'orkerdlSClOSBt in the. patent to Ryan No 958,013. dated May 7, i910, and tosome extent in the earlier patents to Krippendorf No. 579,518, dat dhlarch .23, 1897, and Bohr No. 878.4 "3. dated February l, 190.8. TheGem hm was a hetter insole than the Rochestc r to Moore No s ..:Zl?dated April 3, 1.893, which preceded it, because in the Hero thereinforcing fabric is carried across the leather time stiil'cning this6XClfi liljQl flexilt-le portion 1 and pif rentiug becoming ui d in thelasting on! e: i nt operation on th shoe.

heron-ed l ather is-used, which is a serious feet on thin stock. At thesame time the momy insole an improvement on the {:Jem insole because ofthe greater strength oi the imnginal lip or rib and because the stock atboil: the inside and outside of the lip is oi th same thickness, makingfor a tighter seam and for less damage to the reinforcing lzihric duringthe inseaming opl'zllli'ill. as is well understood by those skilled inthe art. Another, and a serious, detect in the Gem insole, which thelatter types of reinforced insoles overcome, is that the duck or canvas,used as reinforcing fabric, is trimmed in such manner that its ravelededge shows beyond the edge of the insole and gives an unsightlyappearance to the in side of the finished shoe. It has more recentlybeen proposed to combine some of the good feetui s of the Economy andGem insoles in a single insole and some manufacturers are now wring aninsole blank having a ma" llill ii 1 rib like that of the Economy insoleect of reinforcing fabric applied th 'e that of the Gem insole. \niilustrn ion-oi thistype is found in Figure 3 of the Thoma Patent No.1,108,026, dated August 154, lllll. Still this reinforced insole whichmore be termed the Cincinnati insole is imperfect because it does notovercome the serious defect of the fabric-showing, at the shank of theinsole especially, in the finished shoc.

' The object of the present invention is to improve the manufacture ofinsoles in such manner as to produce in reinforced insole whichovercomes all the defects hereii'ibeforc adverted to as present ininsoles of this general typo.

To the awom ilishinent of this obj ct the invention consists in themethod of making r inforced insoles, the preferred manner of p actisingwhich is hereinafter described lfltl defined in the appended claims.

An understanding of the invention will he assisted by reference to theaccompanyin; drawing in which,

Fig. is a transverse section across the 'forepart of an insole blankwith its edge and Fig. 3 is a transverse section across the shank of theinsole of Fig. 2 after having been operated on by the present novelmethod.

In making the insole, the blank 2 which may be of leather or any othersuitable material, is preferably slit at its edge as at 4 (Fig. 1) in aplane usually parallel to the face of the blank. The section 6, on theflesh side, if the blank is of leather, is then upturned to form amarginal lip or rib (see Fig. 2) While the section 8, on the opposite orgrain side of a leather blank, forms the feather of the insole.Reinforcing fabric 10 which is preferably, although not necessarily, inthe form of a wide sheet is then applied to the lipped face of theblank- 2, being beaded or crimped about the lip or rib 6 and extendinglaterally to either side thereof. The fabric may be applied by hand, orby any of the commercial machines supplied for performing thisoperation, and if applied by a machine the fabric, if it projects beyondthe edge of the blank, may be simultaneously trimmed along a linecoinciding with the edge of the blank, as shown in Fig. 2. It will beunderstood that the reinforcing fabric, now generally used, is of theprepared type, that is, provided with a cementitious coating which whencool is dry but which becomes tacky when heated, and itis applied to theblank while in its heated condition. The first application of thefabrig: seldom causes the fabric to lie snugly in the anglesv at theouter and inner sides of the lip or rib and, therefore, a rib tighteningoperation on the reinforced blank is very generally performed. Themachine of application Ser. No. 822,7 57 is preferably used to performthis rib-tightening operation and the insole is passed through thismachine while the fabric is still hot, that is, before the cementitiouscoating has had time to become set and hold the fabric firmly to theblank. This rib tightening machine has tools for pressing on the fabricin the angles at both sides of the lip or rib and causing it to liesnugly against the blank at these points. The rib tightening tools arealso so shaped as to give the reinforced lip or rib an inward set orbend. asshown in Fig. 3 for a purpose hereinafter explained. lurthermore this rib tightening machine is provided with means toconsolidate the stock at the inside of the lip or rib, forming a channelat this point. as shown at 12. (Fig. 3). and reducing the stock justinside the lip to the same thickness as tlfe feather. 'lhe ribtightcning tool for operating in the angle between the lip and feather,in tucking the fabric tightly into the outside angle, acts to draw thefabric slightly witliin the edge of the blank, as shown at 14 (Fig. 3).This is an advantageous way of removing the fabric from the marginalportion of the feather as it leaves the feather unreduced from thethickness which existed before the application of the fabric and,therefore, unweakened. Those skilled in the art will recognize however,that there are other ways of removing the reinforcing fabric from theouter margin of the feather, a1. except as it may be specificallydefined in one or more of the appended claims, it is not essential thatthis step in the production of the novel insole be performed by said ribtightening machine.

As a result of this method of making reinforced insoles the insoleproduced is possessed of all the features of advantage hereinbeforeadverted to, namely,- the lip or rib is sufficiently strengthened, forreceiving the inseam, by two layers of fabric; the stock at both sidesof the lip or rib is of the same thickness, providing for a tight seam;the fabric is removed from the outer margin of the feather so that it isnot visible when the insole is attached to the upper; and the lip or ribis bent inwardly so as to provide a firm support for the channel guideof the welt sewing machine and enable theshoe to be easily held inproper position to receive the inseam stitclm I believe myself to be thefirst to devise a method of making reinforced insoles in which thereinforcing fabric is so applied and shaped as to render it invisibleafter the insole has been incorporated in a shoe, and

especially in so carrying out this method that the feather of the insoleis left unreduced from the thickness which existedbefore the applicationof the reinforcing fabric. The shank portion of the insole is its onlyportion plainly visible on looking into the completed shoe, and,therefore, it will be obvious that the fact that the reinforcing fabricon parts of the insole other than the shank is or is not invisible isimmaterial, the true scope of the invention being found defined in theappended claims.

Having thus described the invention and the preferred method ofpractising it, what is claimed as new is: i

1. The method of making reinforced insoles which comprises providing ablank with a marginal, upstanding lip or rib and outside featherportion, applying reinforcing fabric to the lippcd face of the blank,and removing the fabric from the outer margin of the feather portion, atthe shank portion of the blank at least and without reduction of thethickness of the feather, to cause its edge to lie within the edge ofthe blank.

2. The method of making reinforced insoles which comprises edge slittinga blank, upturning one of the two sections to produce a lip and feather,applying reinforcing fabric to the lipped face of the blank, and

removing the fabriclrvan the outer margin of the feather. al lh shankportion of the blank at lkibl anil without reduction of the tlIlClHH'Sfiol' the l'callu'r; lo cause its edge to lie within the edge ol' theblank.

ing the lip in\\a'r:ll and drawing the fabric inward across the featherinto tlie ang-le outside the. lip until its i-rilge lies within the edgeof the blank. i

4; The ,nrctlu-al of making reinforce(l insoles which coin-prisescutting the marginal ortion of a blank to produce a'lip and a feather.applying reinforcing fabric to the U ped face of the blank.consolidatingthe stock in the angle inside the lip, and drawing thefabric i'nwaril across t'he feather into the angle outsiile the lipuntil its edge lies within the edge of theblank.

7,. That step in the manufactureof reini'orceil insoles which consistsin ren'imiing the previously applied reinforcing fabric from the-outermargin of thefeatherwith out weakening the feather by reducing itsthickness.

(3. That step in the manufacti'ire of reinforced insoles which consistsin drawing the margin of the reinforcing fabric,preqiously a ppliedtothe feather ofan insole blank, inf\\'arill v until its edge lies on thefeather within the edge of the blank.

7. That step in the manufacture of reinforced insolcs having reinforcingfabric eX-' tending over the lip and across the feather which consistsin tucking the fabric into the angle outside the lip and causing itsedge to be drawn within the edge of the insole blank.

S. The method of making reinforced insoles whichco nprisifi pr m -'idinga blank with a marginal, 'npstalu ling lip or rib, making an incomplete.i aplication (if-r inforcing fabric to the lip or rib, trimm ng thefabric along a line such that when completely applied its edge will liewithin-the edge Ofthe olanl; and then coinplet ingthe application ofth'e'fabric. i 4

- S). The method of n'iaking reinforced insoles which comprisespartially applying reinforcing fabric to a lippe-d insole blank at theopposite sides of the lip thereof, trimlining the fabric, and;thereafter completing the a 'iplieation of the fabric by drawing it intothe outside angle between the lip and feather to a position with itsedge lying on the feather within the edge of the blank.-

10. The method .ofm'aking reinforced insoles which comprises providing ablank with a marginal, upstanding'lip or rib and outside featherportion, applying re'inforc ing fabric to the lipfped face of the blank,and removing the portion of the. blank at least, cause its edge to liewithin the edge of the blank. a E.
